An encoded recordable medium includes a programmable read only memory adapted to receive a predetermined code, a storage memory, and a connector for electrically connecting the programmable read only memory and the storage memory to a computer. Particularly it is possible to prepare, with high yields, ethylene polymers having low molecular weights and narrow molecular weight distributions, without the need of using considerable amounts of molecular weight regulators, such as hydrogen. The hub is rotatably mounted on a frame, and the shaft is mounted at least partially internally in the frame. The SOCI may exit the hibernate mode and begin operating in active mode if a physical key connected to the battery is removed. The change and configuration management software tool is automatically deployed to the desired web application server. More specifically, the invention relates to tricyclic \u03b4-opioid modulators.
